Halloween is the one time of year that we seek out scary situations. Some people decorate their houses like a creepy lab or cemetery, others go to haunted houses to see classic monsters and gory scenarios. We dress up like witches, devils, vampires, zombies, and other creatures of the night. What causes us to seek out these frightful situations? Why are we afraid of what we see? What happens when we look at these scary creatures with a scientific lens?
